This paper has designed a temperature-aware charging strategy with adaptive current sequences to improve the charging performance of lithium-ion batteries in cold environments. An integrated battery model with time-varying parameters is established to reveal the relationship among battery electrical, thermal, and aging features.
Currently, external temperature monitoring and early warning are predominantly utilized in lithium-ion batteries (LIBs), but they can't ensure the accuracy of battery safety warnings. Conversely, internal temperature analysis enables precise identification and early warning of thermal runaway events.
In this paper, combined with the internal and external temperature model, the electrolyte evaporation temperature, and the SEI decomposition temperature, a hierarchical early warning method for thermal runaway of lithium battery charging and discharging is proposed, as shown in Table 4.
If one is aiming for a similar charging capacity to the standard CC-CV charging method while emphasizing charging speed, CP-CV can be chosen as the charging algorithm for lithium-ion batteries. For applications that emphasize temperature rise and charging efficiency, CL-CV can be chosen as the charging algorithm for lithium-ion batteries.
The research on the internal temperature of lithium battery mainly includes two parts: experiment and numerical algorithm. In the experimental aspect, the measurement method of internal temperature is mainly explored, such as embedding micro thermocouples into the battery to measure the internal temperature [7, 8].
In the low-temperature environment, the charging time of the two lithium-ion batteries is longer and the discharge speed is faster than the experimental set charging time.
